[sr-dev] [kamailio/kamailio] starting kamailio takes too long (#2613)

[David Villasmil]

did you see

3.10. fetch_rows (integer)

The number of the rows to be fetched at once from database when loading the
routing data. This value can be used to tune the load time at startup. For
1MB of private memory (default) it should be below 3750. The database
driver must support the fetch_result() capability. This parameter is
tunable via the ser cfg framework.

*Default value is “2000”.*

*Example 1.10. Set fetch_rows parameter*

...
modparam("carrierroute", "fetch_rows", 3000)
...


 ?
